Bringing back LE summoner icons

So, I really like how Riot has been bringing back limited edition skins from past Harrowings and such. It's been really good to see some of the ones I never get to. Or to pick up ones I never could before.

Are there any plans to do the same thing with some of the summoner icons that were only available briefly? In particular, I was hoping to snag that Carnival Mask icon for my main account. But I'm sure other icons would be similarly appreciated.
